Calculating Pump Flow Rate Calculating Pump Flow Rate


Pump flow rate calculations are essential in fluid systems, ensuring optimal performance and efficiency. In this article, we will explore the concept of pump flow rate and its importance in various applications. Furthermore, we will discuss different methods for calculating pump flow rate and introduce Linquip’s Pump Flow Rate Calculator, a powerful tool designed to simplify flow rate calculations.


What is Pump Flow Rate?

Pump flow rate, also known as flow capacity or volumetric flow rate, is the amount of fluid that a pump can move within a given time interval. It is typically expressed in units such as liters per minute (L/min), gallons per minute (GPM), or cubic meters per hour (m³/h). The flow rate is a crucial parameter for determining the performance and efficiency of a pumping system.
